..;.-As-pointedf out. above,- the invention is disclosed =-,..herein;with;reference tofthensecuringfof; a, shoeo Vto Fig. `4, it will benoted that the line of drive plication led in my name, to whichreference` may be had for a complete disclosure of. the machine. It willbe understoodthat during the performance of the lasting operation theshoe upper-18r is worked progressively into Alasted. re,- lation to thelast 20 and insole 22, being secured the legs of the staples 24 emergingfrom .the inner surface of the rib 26 and being turned'back into `thesubstance of themrib andclenched by clenching cavities [28 formedy inthe anvil 14. Conveniently the anvil 14 is adjustably mounted 1 asindicated 'at 29 in Fig. 1.

' 'In accordance with the present invention the' Alegs of the staplesare clenched by the clenching cavities 28 of the anvil 14 in asubstantially helical form, as indicated in Figs. 2, 3, 4 and 6, theclenched portion of the staple, moreover, 'being located in the rib 26at its extreme base and ,intheV body of the insole adjacent to the rib,asbest shown in Fig. 2. To accomplish'this the portion of the anvil 14containing the clenching p cavities 28 is positioned against the base ofthe ribas illustrated in Figs. 1 and 2. The forma- -tion of theclenching surfacev of thecavities 28 j is'athree-dimensional curve, thatis to say it is a curved surface Levery cross section of which is acurved line, and it is located out of the line ofv drive 4 ornonsymmetrically with respect to the line of drive as` will be evidentby a Vcomparison of Figs. 4,'y 6, 'land 8. The transverse curvature ofthe Aclenching cavities, that is, theV curvature to successive sections1parallel to lines VII-VII, VIII-VIII of Fig. 4, increases progressivelyfrom [25 :the transverse median'line towardthe end of thev anvil, andthe longitudinal curvature -of the clenching cavities increasesprogressively from decreases progressively away4 from the transversemedian line of the anvil. -Thedeepest ,portion ofl any transverse curvefalls adjacentto the line 'V-V-'of Fig.v 4 which is parallel tothegeneral plane of the 'driver 12, Referring particularly A(represented bya fragment ofthe cross bar of Y' theVstaple' indicated at 30 and thecross sectionv of `aleg of the staple indicated at32) is substantiallyabove and Iparallelto thelin'e V-'-V A*with respectlto which-portions ofthe clenching point aboverthe deepest part of the clenching '1250cavities-thus `deflecting the entering 'ends of the' w legs of thestaple progressively away 'from' each *'othersy'mmetrically with respectto the median 7 --plane of thelstaple and at the Sametime downardl'y(as'viewed'in Fig. 4) andultimately back in that relation by staples 24inserted through .f the marginal portion 16 fof ltheupper' 18` intotherib 26 of the insole 22, the entering ends of entof the United Statesis:

the cavities being located out of the line of drive c'av'ities'adjacenttojth'e line V -HV are syrnmetri ical. Byreference to Figs. 5V and' 6,and to Figs.

7 and 8, Awhich are cross sections'on the lines 3,55 vVII-VII andVH1-#VIII respectively of Figs. 4A andgit will be seen that theclenching cavitiesr "Y are of'such a formation that they Vare struck byth-entering, ends of the legs Aof a staple at a' the general directionfrom which they have come, as indicated in Figs. 5 and 6, the resultbeing a substantially helical or corkscrew clench as shown in Figs. 2and 3 and as indicated by comparison of Figs. 4 and 6.

In order to yfacilitate the positioning of the -lasted relation to theinsole and last of a Goodyear welt shoe are clenched in this fashion theA 'entering f ends'. of' the staple legs are engaged `vvhentheyfemerge'f-rorn the inner surface ofthe rib of the stapleby theclenching cavities 28 of the anvil: 14 and are curved progressivelythrough a substantiallyhelical path backinto the rib 16 95 of the insole22'l and toward the inner surface of the insole, iinally anchoringthemselves' in the insole in a `manner which prevents the rib fromyielding under thetension of the lasted shoe imperi' .Y f f Havingv thusdescribed my invention` what'I claim as new and desire to secure byLetters Pat- 1. A fastening inserting machine having at clenching anviland means for inserting a fasten-405 ing through a workpiece presentedto the Inachine and clenching its entering end against the anvil, acavity in the anvilv havinga concave clenching surface constructed andarranged to be struck by the end of a fasteningat a point nearf'llO "ingsubstantially inthe form of a helix.

n 2. Aistaple insertingmachine'having a driver, a clenching lanvilhaving clenching cavities, and means for causingrelative movement of thedriver and the anvil to insert staples into aworkpieceand toclenchthe-enteringends4 of the legs vof the staples after theyhave passedthrough the work-piece, theclenching cavities of the anvil being locatedrelatively to the path of movement of the driver to cause the enteringends of the staples to strike the cavities near the median line of theanvil, the curvature of the-cavities increasing both transversely andlongitudinally toward the edges of the anvil and` the'deepest part `ofand adjacent to the lateral edges of the anvil to cause the enteringends of the legs of the staples to curve in substantially helical paths.

3. A staple clenching anvil having clenching cavities arranged to clenchthe entering ends of the legs of astaple and formedY and arrangedsymmetrically with respect to the medianjplane of the staple, the'clenching cavities being formed'with surfaces having successivetransverser sections increasing in curvature and having the longitudinalcurvature of the cavities increasing from the transverse median line ofthe anvil toward the ends of the anvil with -thedeepest part of thecurve of any transverse section lo' cated out of the general plane ofthe staple to permit the legs of the staple to strike the surfaces at apoint above the deepest part of the cavities to direct the legs of thestaple progressively and uniformly away from each other and away fromthe plane of the bar and the legs of the staple in the earlier stages ofthe` clenching operation whereby the two legs of the staple are clenchedsubstantially in the form of rightand left-handed heliXes respectively.

4. A staple clenching anvil having clenching cavities arranged to clenchthe entering ends of a staple and formed and arranged symmetrically withrespect to the median plane of the staple,

' the clenching cavities being formed to direct the legs of the stapleprogressively and uniformly away from each other and away from the planeof the bar and the legs of the staple in the earlier stages of theclenching operation and later toward each other but still away from theplane of the bar and the legs of the staple whereby the two legs `of thestaple are clenched substantially in the form of rightand left-handedhelixes respectively each of substantially more than 180 degrees.
